Arduino Math Continued (pythagorean theorum)

NIck Tinkham 12/23/09

/*
* Math is fun!
*/

#include "math.h" // include the Math Library

int a = 3;
int b = 9;
int h;

void setup() // run once, when the sketch starts
{
Serial.begin(9600); // set up Serial library at 9600 bps

Serial.println("Lets calculate a hypoteneuse");

Serial.print("a = ");
Serial.println(a);

Serial.print("b = ");
Serial.println(b);

h = sqrt( a*a + b*b );

Serial.print("h = ")
Serial.println(h);
}

void loop() // we need this to be here even though its empty
{
}

This is a nifty little program where you enter the length of the legs on the triangle, and the Arduino will calculate its hypotenuse.

Programing Arduino

Nick Tinkham 12/18/09

int ledPin = 13;

void setup()
{
pinMode(ledPin, OUTPUT);
}

void loop()
{
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}

This is the program that we made to run the yellow led. The led blinks once every second. It was a very easy code to write.

Robotic Systems - Arduino

I am researching Arduino to find out about its systems and how they work. Here are a few links about Ardunio.

Arduino is an embedded system platform based on a simple open hardware design for a single-board microcontroller, with embedded I/O support and a standard programming language.[1] The Arduino programming language is based on Wiring and is essentially C/C++.[2] The goal of the Arduino project is to make tools available that are accessible, low-cost, low capital investment, flexible and easy-to-use for artists and hobbyists, particularly those who might not otherwise have access to more sophisticated controllers that require more complicated tools.
